JONATHAN CHASE, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO HENRY KELLOGG, JR., OF SAME PLACE.

COAL-BARG E.

SPECIFICATION forming part of Letters Patent No. 494,122, dated March 28, 1893;

Application led May v28, 1889.

To afZZ whom it may concern:

Be it known that I, JONATHAN CHASE, of Boston,county of Suffolk, State of Massachusetts, have invented an Improvement in Coal- Barges, of which the following description, in connection with the accompanying drawings,Vv is a specification, like letters on the drawings representing like parts.

This invention relates to vbarges or vessels especially adapted for the transportation of coal and other granular material, and is an improvement upon the barge or vessel shown and described in another application, Serial No. 282,838, filed by me August 16, 1888.

The barge or vessel is provided with a longitudinal passage-way preferably communieating with an elevator well at its opposite ends, in which are located sprocket wheels over which an endless chain of inverted buckets are revolved, the said endless chain of buckets traveling on a track in the said passage-way and being passed about a sprocket wheel supported above the deck of the vessel by a suitable upright frame, substantially as in the application referred to.

One feature of my present invention consists in providing the longitudinal passageway with side walls, which support one end of removable sections having their other ends suitably supported from the side of the vessel, the said sections when placed in position forming a false bottom for the barge or vessel. The longitudinal passage-way is normally closed by movable knives constituting doors, the said knives being operated preferably from the deck of the vessel, as will be described. The rails of the track referred to rest upon ties, and between the said rails is located a dirt detlector or shed inclined from near the center of the track toward the rails, so that the dirt accumulated below the buckets falls down the inclined shed between the ties, where it can be readily removed, preferably through openings at the bottom of guards preferably made in sections, the said guards forming alleys or passages with the side walls of the passage-way, through which a man may pass.

Another feature of my invention consists in a novel form of bucket.

Another feature of my invention consists in Serial No. 312,436. (No model.)

providing one wall of one elevator well with a valve, preferably a sliding door, through which the coal or other material may be discharged into the buckets when the barge is loaded.

The particular features in which my invention consists will be pointed out in the claims at the end of this specilication.

The barge or vessel A of any usual or well known construction is provided with a longitudinal passage-way A preferably communieatin g at its opposite ends with elevator wells A2, A3, substantially as in the application referred to. The passage-way A is provided with side walls ct adapted to support one end of removable sections c', as shown in Fig. 1,

having their other ends supported as herein l shown by a bracket 0.2 secured to the side of the barge. Each removable section d is preferably provided with a projecting strip cts, see Fig. 2, which overlaps the point or seam between two adjacent sections, the said removable sections when laid in place, forming a false bottom for the barge or vessel upon which the coal or other granular material may be supported.

The barge or vessel A is provided with an endless chain of inverted buckets a4, and preferably of receivers a5 interposed between IOO said buckets. The inverted buckets a4 may be made as shown in Figs. 4 and 6 with their tops or roof a7 made inclined from the front toward the rear end, so that the material falling upon the said bucket is deflected into the receiver a5 between adjacent buckets, the said receiver being composed of a bottom 19 and sides 19', having ears 192 which are fitted on lugs 193 on the outside of the buckets, the said lugs forming bearings for the axles 114 of the wheels 195. The wheels 195 run upon a track located in the longitudinal passage-way, and the rails 196 of the said track are supported upon ties 117.

Between the rails 196 is located a detlectoror shed 198 inclined from near the center of the track toward the rails, so that coal dust or other material falling below the buckets will be deflected toward the rails where it can be readily removed by a shovel, the said coal dust falling from the deflector or shed between the ties 197.

The passage-way A is provided on opposite sides of the track with side guards c forming with the side walls a alleys or passages c through which a man may pass to remove the accumulated dust dac. The side guards c are preferably made in sections which are secured to the bottom of the vessel as by bolts or screws c2, as shown in Fig. 4, and each side guard is preferably cut away at its bottom, as at c?, to permit the operator to remove the accumulated dust dac.

The longitudinal passage-way maybe closed preferably by a series of knives d, shown in Fig. 1 `as on each side of the passage-way, the said knives being movable in suitable guides preferably on the underside of the false bottom. Each knife, as shown in Figs. 1, 3 and l1, is provided with rack bars c1 with which mesh pinions d2 on a shaft C13, see Fig. 11, the said shaft having mounted on it a bevel pinion (14 in mesh with a bevel pinion d5 on a shaft d6, having bearings, as shown in the wall a and bracket a2. The shaft C16 has mounted on it a bevel pinion d8 in mesh with a bevel pinion C19 on an upright shaft C110, eX- tended above the deck of the vessel and as .herein shown through a tube or pipe C112 to protect the shaft from the binding or Wedging action of the coal. The shaft C110 is preferably provided above the deck with a hand wheel, by which the knife connected therewith may be moved forward to close the passage-way Aand cut off the supply of coal', or the said Wheel may be turned to withdraw the knife and open the passage-way for the passage of coal'to the buckets.

To prevent-the sprocket wheels from becoming clogged with the material, as coal, a shield e is provided, the saidvshield being secured to lthe wall of the elevator well as by bolts or screws e', see Fig. 12.

The barge or vessel is provided with a single line of buckets, as shown in Fig. 1, located substantially in the center of the barge, but if desired two rows or lines of buckets may be employed as shown in Fig. 3, there being a line of buckets on opposite sides of the keelson e3, the latter being provided, as shown, with a ^shaped top or cap c4 having its sides extended over the buckets, and with which the knives d co-operate to close the passageway on one or both sides of the keelson.

With the arrangement shown in Fig. 3, the deilector or shed 198 is made in two parts or halves, one on each side of the keelson.

I have herein shown two knives by which to close the passage-way A but it is evident I may dispense with one and provide on one side of the said passage-way substantially the /\shaped top or cap e4, shown in Fig. 3.

By means of the knives d the supply of coal to the buckets may be cut off, so that any desired part of the cargo of coal or other grantilar material may be discharged at one point or station, and the remainder or a partthereof may be discharged at another station.

As shown in Fig. 1, the removable sections a extend over the passage-way A', but if desired the side Walls a may be connected by a roof g, see Fig. 7, having a shoulder g upon which one end of the said removable section may rest.

The roof g is provided at suitable intervals with openings g3, see Fig. 8, preferably having upwardly inclined sides g4 which serve to direct the material toward the opening g3. Each opening g3, as shown in Fig. 7, is normally closed by two knives d, which in this case are supported by guide rails g5 and are made to move in opposite directions to uncover the opening, preferably by levers gs, Q7, the said levers being provided, as herein shown, with a central elongated eye gS into which is extended a pin Q9 connecting each knife to one of the said levers. The lever g6 has one end connected to a rope or chain glo on one side of the longitudinal passage-way, and has its opposite end pivotally secured to the opposite side of the longitudinal passage, and the lever g7 is pivoted to the side of the said passage opposite to the side to which the lever g( is pivoted, and is connected to the rope or chain Q10 after the latter has been passed about a sheave 912, so that when one part or end of the rope or chain is pulled upon, as for instance the end marked 25, Fig. 8, the knives are brought together to close the opening g3, and when the end marked 26 is drawn upon, the knives are moved away from each other, and the opening g3 is uncovered to permit the material to pass through into the buckets. The ends of the rope or chain gl0 will preferably be passed about pulleys gw, see Fig. 15, located in one of the elevator wells, the said ends being extended up to the deck, where they may be secured to a windlass or other mechanism by which they can be readily moved.

Instead of the particular form of inverted bucket shown in Figs. 2 and, I may use any other desired form, as for instance such as shown in Figs. 9 and 13; and to maintain the IOO IIO

endless chain of buckets intact, in case the buckets become separated by the breaking of the pivotal connection of hinge of the said buckets, they are preferably connected together on their underside by ropes or chains Q20 passed through bolt eyes g21 secured to the buckets.

p The vessel will preferably be provided with stanchions g30 to support the removable sections at or near their center.

To facilitate the discharge of material when the barge is loaded, I have provided one wall or bulk-head of one elevator well as A3, with an opening or outlet Q31 normally closed by a slide valve or door Q32, which may be operated in any suitable mannerfrom the deck or from within the said well. The bulk-head referred to has preferably secured to it below the opening g31 a chute or guide Q34.

When the barge is loaded the buckets may be loaded by opening the valve 932, lthus permitting thc coal or other material to descend into the buckets. After the material has been removed from the bulk-head sothat it will no longer run out of the opening gal, the first section of the knives are operated to uncover the opening nearest the bulk-head, and an operator may gain admission to the hold of the vessel through the opening 931 and guide the material through the uncovered opening leading to the buckets.

I prefer to operate the knives as herein shown, but I do not desire to limit my invention to the particular manner shown, as other equivalent means may be employed.

The false bottom is preferably made of removable sections to enable the said sections to be taken down or removed, so that the barge may be used for transporting miscellaneous merchandise. Each removable section when made of wood will preferably be sheathed or covered on its upper side with iron, or the said sections may be made of iron, so that the material will slip toward the passage-way, on a less pitch.
